According to Clara "Papa is psychological". She told me this after he went to work this morning.

Explanation: Clara heard me asking Marc if he was feeling OK this morning, she quickly piped up "do you have a cold, Papa?" His highly sarcastic response was "No, I'm not really sick, it is just psychological, I don't want to go to work".

And, here she is, the performer herself singing Jingle Bells at the top of her voice this afternoon.
